An assessment of a request for change is made by first receiving the request for change. The request for change is compared with a plurality of stored requests for change that are stored in a change database. Then, a computation is made, using learned similarity functions, of a similarity value for each of the stored requests for change with respect to the received request for change. Feedback is received with respect to the similarity values. A training set of data is updated based on the received feedback. The updated training set of data is applied to a learning process, to obtain learned similarity functions. The similarity calculator is updated with the learned similarity functions. The similarity functions can be used to evaluate the risk of changes by looking at the impact of similar past changes.

Decision making based on changes input to a database

A technique for evaluating service level agreement (SLA) violations occurring in a computing system with agreed-upon model for exemptions is provided. The technique includes storing in a memory a model of the SLA and identifying occurrence of an SLA violation in a computing system that is providing services under the SLA. Based on the stored model, the technique further determines if the SLA violation is exempted from a penalty.
